Problem with interbase (firebird-1.5) on FC4 box, httpd-2.0.54, php-interbase-5.0.4-10.5

[Daniel Paul]

Hello there,

because I need interbase (firebird) support in php, I recompiled the actual 
php-5.0.4-10.5 package with interbase support (--with-interbase=shared). When 
I start httpd there is the following message in error_log:

PHP Warning:  PHP Startup: Unable to load dynamic library 
'/usr/lib/php/modules/interbase.so' - object requires: cannot enable 
executable stack as shared object requires: Permission denied in Unknown on 
line 0

phpinfo() shows that php has read the interbase.ini file which contains a 
reference to the interbase.so module, but interbase support is disabled 
(nothing shows up regarding interbase). With selinux set to permissive mode 
(instead of enforcing), there is no such message and phpinfo() shows me, that 
interbase support is enabled.

audit.log shows the following:

type=AVC msg=audit(1138630853.033:10): avc:  denied  { execstack } for  
pid=1886 comm="httpd" scontext=root:system_r:httpd_t 
tcontext=root:system_r:httpd_t tclass=process
type=SYSCALL msg=audit(1138630853.033:10): arch=40000003 syscall=125

auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 comm="httpd" 
exe="/usr/sbin/httpd"

Any help would be truly appreciated.

Thanks in advance,

Daniel
